Vesper,
I have not finished yet. The PCCB's I bought were for a GT3/RS and they do not directly fit at GTS. I am making some spacers to fit around the pins in the hub to hold the rotors in place. I also, need to get Turbo Yellow calipers. I had bought GT3 calipers and they don't sit high enough off the hubs of a GTS. The turbo calipers have "feet" on them so they have the correct height. I am looking for some used ones but may need to buy new. Stay tuned...
